We had 3 text ads in this campaign, getting about 3-4% CTR. I added some new ads (on Wednesday) with different titles and descriptions to see ctr variances. Since I added the new 3 text ads, It looks like G is serving up the new ads a lot more than the old ones. The results for today: The new ads have a CTR of 1.8%, but got served 30% while the old ads got served 4% of the time. Obviously, 1.8% of 30% is generating much higher number of clicks than 4% of 4%, even though 4% of 4% have a higher CTR.
What is the lesson here? Is it that if you change ads frequently, the CTR rate become obsolete?
As more data is captured, the ad with the higher CTR will show more - if you have the optimize ad serving option selected within the campaign settings, that is.
